i'll keep updating the gist with the output of the commands that you make me run for anyone joining the party and trying to get a complete picture :)

@ss:someonex.netSomeoneSerge (matrix works sometimes) You've set an LD_LIBRARY_PATH to cudatoolkit which currently, after a certain regression, inlcudes the stub driver 02:19:46
@ss:someonex.netSomeoneSerge (matrix works sometimes)LD_LIBRARY_PATH is often a footgun02:20:05
@ss:someonex.netSomeoneSerge (matrix works sometimes) * LD_LIBRARY_PATH is often a footgun, it has a higher priority than DT_RUNPATH (which would have lead the linker to /run/opengl-dirver/lib/libcuda.so 02:20:29
@ss:someonex.netSomeoneSerge (matrix works sometimes)Unset LD_LIBRARY_PATH or remove cudatoolkit from there02:20:38

Should work this time: https://github.com/NixOS/nixpkgs/pull/323056
Can I bum a nixpgks-review? xD
I think this only really breaks jax and tensorflow, which are broken anyway šŸ¤”

@hexa:lossy.networkhexa Great having you here! Feel free to enable the (unfun) config.cudaSupport flag at any time now šŸ™‚ 10:41:14
@hexa:lossy.networkhexaWondering what it would take to build and ship unfree redistributable things10:41:57
@hexa:lossy.networkhexa The discussion was running in #platform-governance:nixos.org until the Zulip happened 🫠 10:42:20

Someone of numtide developed nix-ld

@lromor:matrix.orglromor* Someone of numtide developed nix-ld am I right?10:42:57

Wondering what it would take to build and ship unfree redistributable things
I'd love to do that

Nice
Yes, and also https://github.com/numtide/nix-gl-host which might be relevant here
11:42:19
@zimbatm:numtide.comJonas ChevalierFor a while I was running CI on all the unfree packages on https://github.com/numtide/nixpkgs-unfree, but it got really expensive, because my CI doesn't cache failed builds, so it would rebuild broken tensorflows and friends over and over again.11:55:19
@zimbatm:numtide.comJonas ChevalierI have been reading the tensorflow packaging and friends for the past few days, and gained a lot of appreciation for the work that happened there. This goes in the leaderboard of most difficult packaging to work on.12:02:51
@hexa:lossy.networkhexaabsolutely does. also the reason we are lagging behind on the tensorflow source-built package unfortunately.12:17:26
